The building must be in compliance with OSHA regulations for Exterior Building Maintenance (including permanent window washing equipment) in order to receive an OPOS (Operating Procedures Outline Sheet).
An OPOS establishes safe window cleaning and exterior maintenance procedures for buildings and structures.
Issuance of the OPOS requires that all equipment and procedures described in The OPOS are in place and working. The issuance can be delayed where OSHA approvals or rule clarifications are not immediately forthcoming, where there is missing equipment that must be replaced, or modifications have been made or are required to the existing system to assure full compliance with regulations.
